The Mexican Mafia, AKA La Eme, controls the activity inside prisons of California but also other states. It is one of the biggest prison gangs made up of sureño underlings of different varrios that are from Sur 13.

The gang was founded by Luis "Huero Buff" Flores, Cheyenne, and Pegleg in the prisons and by Anacleta "La Annie" Ramirez on the streets.
